 July, 1908 ANNOTATED LIST OF THE BIRDS OF MESA COUNTV, COI,ORADO 171 caslonally seen during the early fall. Breeds thruout May and June, and performs a very slight, if any, vertical migration. [Loxia eurvtrostra stfieklandi. Mexican Crossbill. Carter found this bird breeding at Breckenridge and judging from its established range it is not unreasonable to expect to find it a regular resident, tho at all times rare.] Leucoticte atmtralim Brown-capped Leucosticte. Wi.ter resident. There does not appear to be any locality of sufficient altitude within th[ County bounda- ries to attract these birds during the summer. My only record is that of a large flock observed March 12, 1902, five miles southeast of DeBeque at about 5500 feet. [Aeanthis linarta. Redpoll. Another common bird whose absence from this list is hard to explain. Undoubtedly occurs regularly in winter and probably in some abundance at times.] Astragalinus tristis Imllidus. Western Goldfinch. Prof. Cooke says a few were seen November 11, 1895, by A. H. Howell at Grand Junction. There is no further information at hand regarding this bird. Astragalinus psaltria. Ar- kansas Goldfinch. Summer resident, not uncommon. A late arrival and a late breeder, fresh eggs usually being found in July. More common in the lower portions of the County than higher up. Prof. W. W. Cooke mentions this form as breeding at Glenwood Springs, as it undoubtedly does in more or less abundance all along the Grand River from that point on down to the Utah line. Spinus pinus. Pine Siskin. Resident, common. One of the commonest winter birds up to at least 7000 feet feeding in large floc-ks and frequent- ing the culti/ated sections. Early in April the flocks break up and the birds retire to the higher mountains to breed. During the summer months they are very seldom met with. Junction, October 3. NEST OF THE wESTERN SAVANNA SPARROVq IN DENSE HAY FIELDi MESA COUNTY Mr. E. R. Warren reports a flock from Grand Passer domesticus. English Sparrow. Resident, common. "Miss Myra Eg- gleston reports that they reached Grand Junction during the fall of 1899, a flock of a dozen being seen. This is the first record for Colorado west of the range, and there is nothing to indicate whether these birds reached Grmld Junction from eastern Colorado or have come eastward from Utah. The distance is less from where they occur in Utah, and the mountain passes much lower." (Cooke's Birds of Colorado, 2rid App.) They first arrived in Plateau Valley during the fall of 1904 and in June, 1905, a nest with incubated eggs was destroyed. Since that time they have steadily increased in nmnbers. Pocecetea gramineus confinis. Western Vesper Sparrow. Summer resident,
